What is Myrtle Rust

Myrtle rust is a new-to-Australia fungal disease that was first diagnosed in NSW in April 2010. It affects members of the Myrtaceae family, which includes bottlebrush, eucalyptus, lillypillies, willow myrtle (Agonis spp), austromyrtus, melaleucas etc. See the list of host plants at the National Pests & Disease website. Young plants and soft new growth are most likely to be infected.
